Respond.io charges per Monthly Active Contact (MAC) plus add-ons for AI, extra seats, and advanced features. As your list grows, so does your bill — even for contacts who haven't messaged in months. InboxBase uses a flat fee plus credits: one pool that covers messages, AI, flows, and broadcasts. No per-contact tax.
Respond.io's AI is OpenAI-based and limited in autonomy. InboxBase's Claude-powered agents can read, reply, assign, tag, close, and escalate — with custom personas, tone control, and knowledge base training. In-compose writing tools (tone, translate, grammar, simplify) are also included with no separate AI subscription.
InboxBase covers WhatsApp, SMS, email, Instagram, Messenger, Telegram, web chat, TikTok, Viber, LINE, WeChat, and custom webhooks from one inbox, while also offering 3 workspaces on Scale and unlimited on Enterprise — ideal for agencies managing multiple client brands.
InboxBase also offers native VoIP calling (Telnyx-powered), a TypeScript SDK, and an MCP server — none of which Respond.io currently provides.
